To verify this possibility, the concentration dependence of inflammasome activation in WT and KI cells (in the presence and absence of ATP) selleck compound library was determined. It was found that while inflammasome activation increased in both the cell types with increasing LPS concentrations, WT cells required massive amounts of LPS (>1000 ng/mL) to activate the inflammasome in the absence of ATP, whereas KI cells required only minute amounts of LPS. It thus appears that KI cells do not require co-stimulation by ATP because the small amounts of TLR ligand that enter in the absence of ATP are sufficient to activate the altered inflammasome.

Overall, these data Ulixertinib concentration are consistent with the concept previously suggested from studies of CAPS patients that NLRP3 mutations lead to changes in the conformation of the protein that, in turn, result in a reduced activation threshold and thus an inflammasome capable of responding to reduced amounts of TLR ligand or other activating factors 9, 19. However, NLRP3 may not be able to directly bind to such a wide variety of ligands including PAMP and DAMP, rather an endogenous activator induced by all these upstream stimuli may serve as the direct ligand for NLRP3 (Fig. 1). This concept has also been proposed independently by other researchers 20, 21. NLRP3 KI mice bearing an R258W

mutation raised under pathogen-free facility exhibit spontaneous clinical symptoms similar to those of the counterpart Muckle–Wells syndrome patients. These symptoms consist of poor linear growth, reduced reproductive capacity, impaired hair development and, in many animals, severe dermatitis affecting the 2-hydroxyphytanoyl-CoA lyase ears, top of

the head and tail base area occurring at 6–12 wk of age that is associated with a deterioration of health. The skin lesions were clinically more severe than the urticaria-like skin disease seen in human CAPS and characterized by neutrophilic infiltration of the dermis and epidermis. Spleen and draining lymph nodes were enlarged in the KI mice and showed poorly developed follicles along with a diffuse infiltrate, again containing many neutrophils. However, these KI mice were free of lung, kidney or gut inflammation and the level of circulating inflammatory cytokines was normal 9. The clinical features of mice bearing A350V and L351P mutations were qualitatively similar to those described for R258W mice, but were far more severe. These A350V/L351P KI mice had lifespan measured in days rather than weeks, and had more widespread skin inflammation and inflammatory infiltration (mainly neutrophilic) of many organs, including the joints, sinus, bone marrow and tongue. In addition, there was evidence of “necrotic degeneration” in the gut and kidney.

Control (WT) and KO thymocytes were labeled with different concentrations of CFSE, mixed at a 1:1 ratio and subsequently injected directly into the thymus of a high throughput screening compounds C57BL/6 recipient mouse, at a dose of 4 × 106 cells/mouse, and analyzed 3 days later for developmental progression. CD4+ or CD8+ T cells were

sorted by negative selection using CD4+ T and CD8+ T cell kits and magnetized columns (Miltenyi Biotech) according to the manufacturer’s specifications. Briefly, cells were labeled with biotin-conjugated antibodies (against CD8a (or CD4), CD11b, CD11c, CD19, B220, DX5, CD105, Ter119, and anti-MHC class II) followed by binding to antibiotin beads. The labeled cells were passed through magnetized columns to deplete all non-CD4+ or non-CD8-α+ T cell fractions, thus resulting in purified CD4+ or CD8+ T-cell populations. Subsequently, the purified cells were washed with sorting buffer (PBS supplemented with 2 mM EDTA and 2% FCS), followed by counting and resuspension in DMEM-10 media or PBS. A proliferation assay using thymidine incorporation was carried out as described [45] with minor modifications. Sorted cells were used at a concentration of 1 × 105 cells per well together with 2 × 105 cells per well of irradiated (2000 rads) splenocytes and appropriate stimuli at indicated doses for 3 days. A total of 1 μCi 3H-thymidine was applied to each well

for the last 18–20 h of the 3-day culture period. After cell culture, cells were harvested with the FilterMate Universal Harvester (PerkinElmer, Sheleton, CT, USA) on glass fiber filters (Wallac) and counted with MicroBeta Trilux 1450 LSC (PerkinElmer) Y-27632 chemical structure using dedicated software. In CFSE assays, sorted cells were stained with 2 μM CFSE and incubated oxyclozanide for 72 h with appropriate stimuli at indicated doses. After incubation, CFSE-labeled cells were stained with appropriate antibodies and CFSE dilution within Vα2 positive cells was analyzed using a FACS Calibur cytometer. For adoptive transfer of transgenic T cells the experiments

were performed as previously described [46] with minor modifications. C57BL/6 mice were first immunized in the footpad with OVA protein or with OVA-coated beads in the presence of CFA followed by adoptive transfer of 5 or 10 × 106 cells (labeled with CFSE) from OT1 and OT2 transgenic mice, respectively. Three days after transfer, the proliferation of CFSE-labeled cells in the draining lymph node, within Vα2 positive cells, was analyzed by FACS. For evaluation of homeostatic cell expansion, purified OT1 or OT2 cells stained with CFSE were injected i.v. into RAG recipients (on the C57BL/6 background). The RAG recipients were left untreated for 2 weeks and splenocytes were harvested and analyzed. The proliferation of CFSE-labeled Vα2+ cells was analyzed by FACS and the absolute cell number of Vα2+ and CFSE+ DP cells was calculated.

Renal function continued to decline over the next 48 h. A renal biopsy was performed. This demonstrated an interstitial nephritis check details (Fig. 1). There were no vascular changes. Direct immunofluorescence showed granular positivity to C3c within glomeruli and negative reactivity to all other antibodies. Electron microscopy showed swollen and convoluted epithelial cells pushing into urinary spaces. Foot processes and basement membrane were within normal limits. Management consisted of simple analgesia and i.v. rehydration. Renal function improved over the next 72 h. A 22 year-old man presented with 2 days of constant bilateral flank pain radiating

to the groin. There was an associated fever but no urinary symptoms. Past medical history CAL-101 molecular weight was unremarkable and he denied any regular medications. Further questioning identified that he used cannabis oil regularly and had recently experimented with benzylpiperazines 3–4 days prior to admission. At presentation, he was febrile at 38°C and in pain. Blood pressure was 124/62 mmHg. Cardiovascular and respiratory examinations were otherwise non-contributory. Abdominal examination demonstrated bilateral renal angle tenderness only. No antibiotics

were administered. Urinalysis revealed microscopic haematuria (RBC 50–100 × 109/L), sterile pyuria (WBC 50–100 × 109/L), proteinuria (+ on dipstick and protein/creatinine ratio 21 g/mol) and no glycosuria. Culture was negative. Selleck Ixazomib Biochemistry demonstrated acute kidney injury with a serum creatinine of 210 µmol/L. A CT urogram was performed which demonstrated two normal-sized kidneys with no evidence of renal calculi. ANCA was indeterminate but proteinase 3 (PR3) and myeloperoxidase (MPO) antibodies were not elevated. Antinuclear antibodies (ANA) and anti-GBM were not detected. Complement proteins (C3 and C4) were in the normal range. Streptococcal serology was negative. Renal function

continued to decline reaching a peak of 280 µmol/L. A renal biopsy was performed. This demonstrated a mild mesangioproliferative glomerulonephritis (Fig. 2). There were no vascular changes. Immunofluorescence was negative to IgG, other immunoglobulins and complement. Electron microscopy was non-contributory. Due to continuing renal flank pain and deteriorating renal function, an empiric trial of corticosteroids was commenced. This was followed by a dramatic symptomatic improvement with a rapid resolution of renal failure. Therefore, it is possible that the changes seen on renal biopsy may be due to a direct effect of BZP and or metabolites, given the absence of any other identifiable causative agent. N-benzylpiperazine-based party pills are consumed by many users, without any significant toxic effects.

Typically, cells and aAPC (1:1 ratio) were cultured for 5 h at 37°C. Intracellular

IL-2 and IFN-γ content (mAb were from BD) were determined as described Tyrosine Kinase Inhibitor Library previously 57. In total 50 to 100×103 CD4+ events were generally collected in the lymphocyte gate on a FACS Calibur. The total number of Ag-specific IL-2+/IFN-γ+ T cells was determined by multiplying the percentage as detected in flow-cytometry analyses by the total number of Trypan Blue-negative LN cells. Cytokine release induced by control aAPC remained within background levels (Fig. 1B, second row) and was subtracted from LACK-induced release in all bar graphs. Statistical analyses were performed using unpaired two-tailed Student’s t-test. Statistical significance: p<0.05.

“Cell-mediated immunity directed against human papillomavirus 16 (HPV-16) antigens was studied in 16 patients affected with classic vulvar intra-epithelial neoplasia (VIN), also known as bowenoid papulosis (BP). Ten patients had blood lymphocyte proliferative T cell responses directed against E6/2 (14–34) and/or E6/4 (45–68) peptides, which were identified in the present study as immunodominant among HPV-16 E6 and E7 large peptides. Ex vivo enzyme-linked immunospot–interferon (IFN)-γ Methane monooxygenase assay was positive in three patients who had proliferative responses. Twelve months later, proliferative T cell responses remained detectable in only six women and the immunodominant antigens remained the E6/2 (14–34) and E6/4 (45–68) peptides. The latter large fragments of peptides contained many epitopes able to bind to at least seven human leucocyte antigen (HLA) class I molecules and were strong binders to seven HLA-DR class II molecules. In order to build a therapeutic anti-HPV-16 vaccine, E6/2 (14–34) and E6/4 (45–68) fragments thus appear to be good candidates to increase HPV-specific effector T lymphocyte responses and clear classic VIN (BP) disease lesions.

Over the years, this polysaccharide has been referred to as a PS/A by this research group. Later, Christensen et al. (1990) described a slime-associated antigen (SAA) isolated from the same strain and having a similar function. SAA was claimed to be different from PS/A. However, Baldassari et al. (1996) suggested that SAA and a hexosamine-containing polysaccharide intercellular adhesin (PIA) of S. epidermidis strains RP62A and 1457, high throughput screening assay described at that time by Mack et al. (1994), could be the same antigenic molecule. Mack et al. (1996) were the first to elucidate the chemical structure of PNAG (called, according to its biological properties, PIA). Using a combination

of analytical methods and nuclear magnetic resonance (NMR), PIA was identified as a linear β(1,6)-linked N-acetylglucosaminoglycan containing c. 130 N-acetylglucosamine (GlcNAc) residues, partially substituted with O-succinyl groups, partially de-N-acetylated and apparently phosphorylated (Mack et al., 1996). The genes encoding PNAG biosynthesis are

organized in the icaADBC (intercellular adhesion) operon, which consists of four ORFs (Heilmann et al., 1996; Gerke et al., 1998) with a transcriptional repressor gene, icaR, located upstream and transcribed in the opposite orientation (Conlon et al., 2002). The ica locus was later found in a number of S. aureus strains, and its presence was related to the ability to form a biofilm in vitro (Cramton et al., 1999). A recombinant JQ1 cost strain of Staphylococcus carnosus (pCN27), containing icaABC of S. epidermidis RP62A, unlike the parent S. carnosus strain, which is biofilm-negative, was adherent to glass and revealed the ability to form intercellular aggregates as well as to produce PNAG (Heilmann et al., 1996). McKenney et al. (1998) subsequently demonstrated that the recombinant S. carnosus (pCN27) antigen was identical to PS/A and ‘chemically related’, but distinct from PIA in molecular size, solubility, and substitution of the majority of the amino groups of the glucosamine residues with succinate. This polymer,

named poly-N-succinyl-β-(1,6)-glucosamine (PNSG), was suggested as a potential vaccine candidate against staphylococcal infections (McKenney et al., 1999, 2000). However, Palmatine subsequent studies carried out by the same group showed that the presence of the N-succinyl substitution was an analytical artefact (Joyce et al., 2003). These authors used a ‘PS/A overproducing strain’S. aureus MN8m, and the corresponding polysaccharide was named SAE (S. aureus exopolysaccharide). Detailed NMR studies, in combination with the chemical modifications, allowed a complete assignment of NMR spectra of SAE. According to Joyce et al. (2003), the main differences between SAE and PIA were phosphorylation (absence of a phosphate substitution in SAE) and molecular mass [>300 kDa for SAE and ∼30 kDa for PIA (Mack et al.

67 Key findings of the review were: No controlled trials of microalbuminuria screening

were identified. Assessment of proteinuria by spot protein: creatinine ratio is appropriate for macroalbuminuria (100% sensitivity, 92% specificity).68 However this is not sufficiently sensitive for assessment of microalbuminuria. Previous studies have shown the inherent variability in 24 h AER to be in the range of 40–50%.69 This variability is thought to be related to such factors as posture, activity level, diet and glycaemic control. The variability of overnight AER has been shown to be similar to 24 h collections however, the AER in overnight urine samples is 25% lower compared with 24 h urine samples, and has a lower intra-individual variability.70 Screening tests Paclitaxel purchase are designed to maximize true positive results (i.e. high sensitivity) at the expense of performing a greater number of confirmatory tests. Several studies have

examined the relationship between AER and ACR performed on the same timed urine sample,23,71–74 however, only 2 of these took gender into account.23,71 A number of studies have also compared ACR on a spot urine or early morning sample with a timed AER,70,74–77 however, none of these studies were stratified by gender. In these studies timed urine collections were used as the gold standard for comparison. Using the recommended cut-off values, the sensitivities of spot BCKDHA ACR in these studies were ≥88%. However different definitions for microalbuminuria OSI-906 molecular weight on the timed collections (15–30 µg/min) as well as varying definitions for a ‘positive’ ACR level (2.0–4.5 mg/mmol) were used. Because of high intra-individual variability, transient elevations of AER into the microalbuminuric range occur frequently. The 95% CI for a sample with AER of 20 µg/min, assuming a coefficient of variation of 20%, are 12–28 µg/min (one measurement), 14–26 µg/min (two measurements) and 15–25 µg/min (three measurements).78 Therefore, clinical assessment should be

based on at least two measurements taken over 3–6 months. Another option for assessment of albuminuria is the ACR which is usually performed on an early morning urine but can also be performed on a random sample. The use of ACR for assessment of microalbuminuria is easier and less time-consuming for the patient than measurement of AER. ACR measurements are particularly useful for screening purposes and for assessing the effects of treatment. For instance, measurements at every visit can be used to evaluate the albuminuric response separately from the blood pressure response during titration of antihypertensive therapy. Comparisons of ACR to the gold standard AER have been made in several studies. All the studies show satisfactory sensitivity (80–100%) and specificity (81–100%) (see Table A3).

Changes in protein antigen processing and T-cell activation have also been reported in CGD 35, while studies using human cells have reported increased pro-inflammatory and decreased anti-inflammatory mediators when compared with healthy controls 34, 36–38. We focused upon a recently described family of GlyAgs expressed by commensal and pathogenic bacteria (e.g. S. aureus, RXDX-106 mw S. pneumoniae, and B. fragilis) that have been shown to induce abscess formation via CD4+ T-cell activation 12, 16, 20, 23, 39. Lack of intact αβ T-cell receptor expression or

blockade of co-stimulatory pathways in mice translates into a failure to develop abscesses in response to GlyAg 24. GlyAgs require processing via NO-dependent oxidation 20, 21, 23 and presentation on MHCII molecules

16, 20, 23, providing an unexpected link to oxidative disorders. Our results reveal that CGD mice showed a dramatically increased immune response against GlyAgs, resulting in more frequent and severe abscesses. This differential response was mediated by APCs rather than neutrophils as might be expected and appears to be a result of increased NO and more efficient GlyAg processing. Likewise, the CGD phenotype was transferrable to WT animals via APC transfer, which indicates that the difference in T-cell activation is due to changes in the APC and not the responding T cells. Although we cannot completely rule out direct NO effects on responding T cells, it is clear that NO is required for processing 20, 23 and that Thiamet G CGD APCs are better Vemurafenib concentration GlyAg processors than their WT counterparts. The NADPH oxidase complex is also known to maintain a neutral pH environment within endo/lysosomes 35, and thus changes impact acid-dependent

protein antigen processing. In fact, CGD favors vesicular acidification and increased conventional antigen proteolysis 35. In sharp contrast, GlyAg processing is dependent upon a neutral pH and acidification stops GlyAg processing in cells 40. As a result, one might expect the CGD cells to process GlyAg less than the WT counterparts due to increased acidification, yet we observed the opposite. With the role of NO firmly established within this pathway 20, 23 and together with the ability to ameliorate the CGD effect by iNOS inhibition and the effectiveness of APC transfer into WT animals, we conclude that CGD results in GlyAg hyperresponsiveness because of increased GlyAg processing by resident APCs via increased NO levels, resulting in greater T-cell activation and downstream sequelae. Another unexpected observation was that the level of IL-1β, used as a crude measure of inflammation, was not altered in CGD cells. While this may seem counterintuitive, recent evidence in humans has indicated that asymptomatic CGD patients do not make more IL-1β in response to a number of stimuli compared with healthy controls 41.

After electrophoresis, the proteins were blotted onto a PVDF membrane according to BGB324 concentration standard protocols. After blocking in 5% non-fat milk, the membrane was incubated with the appropriate primary antibody (anti-iNOS, 1 : 500 or anti-SOCS-1 1 : 1000) overnight at 4°, and with the appropriate secondary antibody (1 : 10 000) (GE Healthcare, Waukesha, WI) for 2 hr at room temperature. Equal protein loading was shown by re-probing the membrane with an anti-actin antibody (1 : 10 000) (Sigma) and with

the appropriate secondary antibody. After this incubation period, the blots were washed several times with saline buffer (TBS/T – 25 mm Tris–HCl, 150 mm NaCl, 0·1% Tween) and incubated with ECF substrate (enhanced chemifluorescence substrate) (alkaline phosphatase substrate; 20 μl ECF/cm2 of membrane) for 5 min at room temperature and then submitted to fluorescence detection at 570 nm using a Molecular Imager Versa Doc MP 4000 System (Bio-Rad). For each membrane, the analysis of band intensity was performed using the Quantity One software (Bio-Rad). Nitric oxide production was assessed by the Griess Reagent System (Promega Corporation, Madison, WI), a colorimetric assay that detects the presence of nitrite (), a stable reaction product of nitric oxide (NO) and molecular oxygen. Briefly, 50 μl cell medium, collected from each well, was incubated

buy PF-562271 for 5 min with 50 μl sulfanilamide, followed by a further incubation of 5 min with 50 μl of N-1-napthylethylenediamide. The optical density of the samples was measured at 540 nm in a microplate Dichloromethane dehalogenase reader and the nitrite concentration was determined by comparison with a standard curve obtained for a solution of sodium nitrite prepared

in RPMI-1640. Immunocytochemistry studies were performed in N9 microglia cells according to established protocols. Briefly, following transfection and LPS exposure, cells were washed twice with PBS and fixed with 4% paraformaldehyde in PBS for 20 min at room temperature. The cells were then permeabilized for 2 min with 0·2% Triton X-100 and non-specific binding epitopes were blocked by incubating the cells for 30 min with a 5% BSA solution prepared in PBS. Cells were incubated overnight at 4° with primary antibodies against the CD11b integrin (1 : 500) and α-tubulin (1 : 1000) prepared in PBS containing 1% BSA. Following two washing steps with PBS, cells were incubated for 2 hr at room temperature with the respective secondary antibodies (anti-rat Alexa Fluor-594 conjugate and anti-rabbit Alexa Fluor-488 conjugate; Molecular Probes, Leiden, the Netherlands) diluted 1 : 500 in PBS containing 1% BSA. Finally, all coverslips containing the samples were rinsed twice in PBS and incubated in the dark with DAPI (1 μg/ml) for 5 min, before being mounted on glass slides using Moviol (Sigma).

We have demonstrated that co-transfer of allospecific Treg cells at the time of donor cell transfer can effectively control the expansion of donor alloreactive and autoreactive T-cell clones to prevent cGVHD induction, and as such, they present a more refined cell therapy Galunisertib chemical structure for blockade of disease in a complex immune network of cellular components and events. Female (6–12 weeks old) CB6F1 (C57BL/6xBALB/c F1, H-2bxd) CBA/Ca (H-2k), C57BL/6 (B6) (H-2b), BALB/c (H-2d), mice were purchased from Harlan Ltd (Bicester, UK). C57BL/6.Kd (BL/6 transgenic for Kd) and OT-II and TCR75 TCR transgenic mice (recognise

Kd peptide:H2-Ab) (provided by Pat Bucy, University of Alabama Birmingham, USA) were bred and maintained in the BSU facility of King’s College London under specific pathogen-free conditions. All procedures were performed in accordance with the Home Office Animals Scientific Procedures Act of 1986. Chronic GVHD was induced by transfer of 7 × 107 B6 splenocytes (or pooled with 4 × 106 Treg cells) intraperitoneally into CB6F1-recipient mice. Animals were monitored biweekly

for weight loss condition and scleroderma in addition to peripheral Selleck Lapatinib blood monitoring of engraftment and serum autoantibodies. At 7 weeks post-GVHD, peripheral blood, serum, spleen and lymph nodes were harvested for subsequent immunophenotyping, described below. Splenomegaly was measured by weighing whole dissected spleens. Kidneys were snap-frozen in Optimal Cutting Temperature OCT embedding medium

(EMS, PA, USA) and stored at −80°C until analysis. Absolute numbers of donor (H-2Kd−) and recipient (H-2Kd+) cells were determined by counting total splenocytes obtained from single-cell suspensions and extrapolating from the percentage of H2Kd+/− cells detected by flow cytometry. Kidney cryostat sections (5 μM) were collected on polylysine-coated slides, air-dried, and acetone-fixed, dried and incubated with anti-mouse IgG1-FITC (Serotec, Oxford UK) before washing in PBS/FCS and examination by fluorescence microscopy. Serum was analysed for anti-single-stranded DNA IgG1 and IgG2a autoantibodies HSP90 using calf thymus DNA (Sigma) and IgE titres by ELISA as described previously [49]. Donor splenocytes were prepared as single-cell suspensions of spleens and lymph nodes and erythrocytes lysed. Splenocytes were depleted of CD25+ cells by incubation with biotinylated anti-CD25 antibody (clone 7D4; BD Biosciences, UK) for 20 min 4°C, followed by incubation with streptavidin microbeads (Miltenyi Biotec) for 15 min. Cells were magnetically depleted and the unbound fraction either used directly or depleted of further cell subsets for cGVHD induction.

The PCR was performed for 1 cycle of 94 °C for 3 min, then 30 cycles of 94 °C for 30 s, 60 °C for 30 s, 72 °C for 45 s and then a final 3 min at 72 °C. PCR products were run on 1.5% gel stained with ethidium bromide and visualized by UV light–generating bands (Fig. 1B). Pearson’s χ2 test was used to examine differences in characteristic

variables and the distribution of genetic polymorphisms. Odds ratio (O.R) and 95% confidence interval (CI) were calculated using JAVASTAT. All epidemiologic variables were determined using IBM SPSS Statistics 20 software, where student’s t-test is used to evaluate continuous variables, and χ2 test, for categorical variables. The gene–gene interaction for SNPs was analysed by nonparametric multifactor dimensionality Opaganib manufacturer reduction (MDR

version 2.0 beta 8.4) analysis. Distribution of alleles and deviation of genotype frequencies were tested by using Hardy–Weinberg equilibrium (HWE). P < 0.05 was considered to be statistically significant for all the tests except HWE. Bonferroni correction, an adjustment made to P values, was used to reduce the chances of obtaining false-positive results (P < 0.0005). The demographic profile of tuberculosis cohort was studied. The mean age of the patients (50 males and 50 females), their HHC (44 males selleck products and 56 females) and HC (54 males and 46 females) was 27.4 ± 13.9, 34.8 ± 10.7 and 30 ± 10.7, respectively. TST positivity was observed in patients and HHC with a significance of P < 0.0001. Mean BMI was found to be 16.8 ± 4.25, 22.6 ± 6.85 and 23.7 ± 4.09 in patients, HHC and HC, respectively, and there was significant difference in patients versus HHC and patients versus HC (P < 0.001 and P < 0.0001) (Table 1). 0.15a Pts versus HHC 0.17apts versus HC The genotype frequencies of IL-1 β (+3954 C/T) polymorphism did not vary significantly between TB patients and HC (P < 0.32, 0.395 and 0.89 for CC, CT and TT ADP ribosylation factor respectively). CC genotype was found to be significantly associated with HHC versus HC (P < 0.03, OR = 1.833 and 95% CI = 1.1–3.35) while Bonferroni correction

was not significant. Frequency of alleles did not differ significantly in all the subjects with T allele more frequently found when compared with the C allele (Table 2). IL-1β (+3954 C/T) was found to be in Hardy–Weinberg equilibrium with P > 0.05 (χ2 = 0.08). In IL-10-1082 G/A polymorphism, GG (P < 0.005, OR = 0.219 and 95% CI = 0.059–0.735) and GA (P < 0.0001, OR = 2.938 and 95% CI = 1.526–5.696) genotypes were found to be significantly associated with patients versus HC. GA (P < 0.0001, OR = 0.194 and 95% CI = 0.069–0.516) and AA (P < 0.0001, OR = 4.612 and 95% CI = 2.225–9.702) genotypes in HHC versus HC have shown significant association. Allele frequency was found to be similar in all the subjects (Table 3).
